For toddlers and preschoolers (ages 2–5), potassium phosphate used on the skin is low risk. It’s commonly used to help balance product pH and isn’t linked to cancer, allergy, or developmental harm in the reviewed data.
Use products that contain this ingredient as directed. Prefer rinse-off products (like shampoos or washes) or products made for children. Avoid applying to broken, sore, or very inflamed skin. Keep the product away from the child’s eyes and mouth. If you’re trying a new product, test a small patch on the child’s arm and wait 24 hours to check for redness or rash.
There is a small chance of skin, eye, or breathing irritation reported in ingredient reviews (source: Cosmetic Ingredient Review). If you see redness, swelling, a rash, eye irritation, or if your child has trouble breathing after contact, stop use and seek medical care. Regulatory notes (FDA and Environment Canada) indicate the ingredient is acceptable for limited uses and is not expected to be systemically toxic, which supports its low-risk rating for topical use in young children.
